Dunn gives you a bit of position flexibility when your draft picks comes up and Jeter is simply a better bet than Stanton or Ells when it comes to keepers. Think of it this way, if you don't keep Jeter, and Reyes goes right before you in the draft, you're somewhat screwed. On the other hand, if you don't keep Stanton or Ells, you have ample opportunity to draft a decent OF or a 1B (if you want to move Dunn to OF).
